Here, we're making a DataFrame called epa_df which will sum up team EPAs for each play and we'll also count the number of plays. Next, we'll load in 2020 play by play data via nflfastR. In addition, weve adjusted clock plays, with. Team defenses with more negative EPAs are better defenses, while team defenses with more positive EPAs are worse defenses.įirst things first, load up your Google colab or jupyter notebook and import the libraries we'll need for this post.
